Hi Andrew,
thanks a lot for your help. Today we discovered what
our real problem was:
After "playing" a little bit with the php-scripts that try
to connect to the IBM DB2, we set the optional parameter
Cursortype when calling odbc_pconnect(....).
And the exciting thing: When we set the cursor type
to SQL_CUR_USE_ODBC Cursor Type, then
the whole query speed up from 1 till 10 seconds
to 0.2 till 0.3 seconds for 100 records. Amazing!!!
Therfore, PHP is just almost fast as calling the DB2
from Servlets using JDBC (don't take too much care
about the speed at whole: the database was on a
completely other location, so the whole connection
was made over a slow network connection).
I hope this helps when other encounter the same
problem when trying to connect to DB2 from
PHP.
Kind regards,
Christian Szardenings
